Section/Subsection Heading Footnotes Duplicated

[spidersouris]

Description of Issue

Defining a footnote on a section/subsection heading (level 1 or 2) duplicates it.

Minimal Example

#import "@preview/touying:0.5.2": *
#import themes.simple: *

#show: simple-theme.with(aspect-ratio: "16-9")
#show heading: it => text(fill: red, smallcaps(it))

= Title#footnote("this is a duplicated footnote")

== First Slide#footnote("this is another duplicated footnote")

=== 123#footnote("this footnote is fine though")

Hello, Touying!

Hello, Typst!

Current Behavior

It seems that footnotes are applied once to the section/subsection title (in the header) and once to the slide title? The screenshot below shows that footnote 1 first appears on page 2 next to the "First Slide" section title, and a second identical footnote (numbered 2) appears on the very first slide next to "Title".

There is currently no good solution for this, but try not to use footnote in the heading.
